Coin Jackson, Korea's upcoming girl group, has released an official photo in anticipation of their debut. The girls will deliver music that's been described as 'hip hop a capella'. It's a genre that many are not familiar with, and so the hype for the group is already quite high - the photo released today has only heightened interest, since Coin Jackson appears to be different from the typical 'cutesy' girl group. In this photo, they look like they're going for a tougher, sassier look, as seen by their black leather outfits. Their company,�PPP Entertainment said, "Though they haven't debuted yet, they've received a game CF offer, as well as love calls from Japan and China. Their debut track 'Feedback' will showcase their powerful voices, and their performance will be nothing short of energetic." The group will debut in the beginning of February.
